Regardless of water controller or transceiver installation, all Rinnai water heaters must only beinstalled by an Authorised person.

Water controllers, transceivers and water heaters do not contain user serviceable parts and must onlybe serviced and repaired by an authorised person.

Keep this manual in a safe place for future reference.

All dimensions referred to in this manual are in millimetres, unless otherwise specified.

A WARNING ABOUT HOT WATER

RADIO COMMUNICATIONSRinnai wireless water controllers are classified as short range radio communications devices andreferred to as Low Interference Potential Devices (LIPD’s) in AS/NZS 4268:2003*. As such, theyoperate in the same radio frequency spectrum as many other devices classified as LIPD’s such asgarage door openers and keyless automobile entry systems. Although interference with other LIPD'sis unlikely, it is not guaranteed interference will not occur.

Rinnai wireless water controllers must not be used in the vicinity of other devices if radio interferencewith such devices could result in a dangerous situation, unless it is verified that interference will notoccur. Possible examples are medical devices and fire alarms.

*AS/NZS 4268:2003 ‘Radio Equipment and systems – short range devices – Limits and methods ofmeasurement’.

Excessively hot water is dangerous, especially for youngchildren and the infirm. Rinnai water controllers allow you tocontrol the temperature of hot water to safe levels.

Water temperatures above 50°C can cause severe burns. Thosemost at risk are children, disabled, elderly and the infirm.

ALWAYS......

Test the temperature of the water with your elbow before placingyour child in the bath, also carefully feel water before bathing orshowering yourself.

Supervise children whenever they are in the bathroom.

Make sure that the hot water tap is turned off tightly.

CONSIDER.....

Installing child proof tap covers or child resistant taps (bothapproaches will prevent a small hand being able to turn on thetap).

Setting your appliance at a maximum temperature of 50°c(contact Rinnai Australia).

NEVER….

Leave a toddler in the care of another child. they may notunderstand the need to have the water temperature set at a safelevel.


GENERAL WATER CONTROLLER INFORMATION

Water controllers allow precise temperature control by the user. When used correctly, the hot waterunit will deliver the selected temperature, even when the water flow is varied, or more than one tap isin use. Each remote controller can be individually programmed, however the water heater can onlydeliver one set temperature at any time. The available temperatures (°C) are as follows:

Master Controller (used in kitchen):

37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 48, 50, 55°C* (60, 65°C HD models only)

Bathroom Controller (used in bathrooms, ensuites, toilets and laundry):

Hot Water Delivery: 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 48, 50°C

Whilst hot water outlets are open the set temperature may be lowered. However the set temperaturecannot then be raised above 43°C. In addition transfer of 'priority' between controllers is not possible.These are safety features.

Suggested temperatures are:

Kitchen 50°C ~ 55°C*, Shower 37°C ~ 43°C* Temperature may not be available on all installations. Rinnai water heaters can be programmed to deliver higher temperaturesvia the kitchen controller. Contact Rinnai for more details.

These temperatures are suggestions only. You may find higher or lower temperatures morecomfortable. Maintaining lower temperatures helps save energy. To obtain water temperatures lowerthan 37°C simply add cold water.

The temperature of outgoing hot water is constantly monitored by a built-in sensor. If the temperatureof the outgoing hot water rises to more than 3°C above the selected temperature shown on the digitalmonitor, the burner will automatically go out. The ‘In Use’ indicator will also go out. The burner willignite again once the outgoing hot water temperature falls to that shown on the digital monitor.

Wireless water controllers can be fitted along with wired 'Universal' and 'Deluxe' water controllers.Wireless and Universal water controllers allow temperature selection only. Deluxe water controllersallow temperature selection, have a clock function and on the Deluxe Bathroom water controller BC-100V a shower saver / bath fill function is also available.

Available configurations for Wireless and Wired Water Controllers :

The MC-503RC Wireless water controller is a water resistant device, howeverexcessive exposure to water such as immersion may result in damage to thecontroller.

• DO NOT immerse the controller into water. • AVOID direct exposure to water or steam as these conditions may cause a

malfunction. • ALWAYS AVOID exposure to water when the battery compartment is open.

When cleaning your water controller use ONLY a damp cloth and a mild detergent.

For Wireless Only Installations

A maximum of 4 wireless water controllers can be fitted with thefollowing limitation:Only ONE MC-503RC can be set as the Master Controller.

For Combination Wired & Wireless

Installations

A maximum of 4 water controllers can be fitted. Any combination ofdeluxe, universal and wireless controllers can be used with the followinglimitations:Only ONE master controller can be installed. This can be a MC-100V, aMC-91Q (when programmed as a master controller) or a MC-503RC watercontroller. Note that when a MC-100V is fitted it will always function as amaster controller, this is the default setting and can not be changed. Up to TWO BC-100V water controllers can be installed.The FOURTH water controller in any installation MUST BE a MC-503RCor a MC-91Q.

TRANSFERRING PRIORITY BETWEEN WATER CONTROLLERS
To control the water delivery temperatures when using two or morecontrollers it is necessary to have priority transferred to the watercontroller you wish to use.

An illuminated Transfer indicator confirms that the desired watercontroller is in control of the water delivery temperature.

If the Transfer indicator is not illuminated press the ‘Transfer’ button to transfer priority to the desired water controller.

The Transfer indicator on the water controller will now illuminate toindicating that priority has been transferred and that the water heater isready to supply hot water once a hot water tap is opened.

Whilst hot water taps are open transfer of 'priority' between controllers is not possible.This is a safety feature.

HOT WATER CONTROLTemperatures higher than 50°C should only be able to be selected on the controllerlabelled ‘Master’ controller (used in the kitchen), not on those labelled ‘Bathroom’controllers. This helps minimise the risk of burns.

The wireless transceiver has been incorrectly assigned if temperatures in excess of50°C are able to be selected on controllers used in bathrooms, ensuites, toilets andlaundries. Re-assign the wireless transceiver if this is the case. See “UN-ASSIGNINGAND RESETTING WIRELESS WATER CONTROLLERS” on page 14 and “INSTALLINGWIRELESS WATER CONTROLLERS” on page 13

USING CHILD LOCK FUNCTIONThe Child Lock function is designed to prevent small children or the infirmfrom operating the wireless controllers.

To Activate the Child Lock

To activate the Child Lock function press the button for 3 seconds. TheChild Lock indicator will illuminate to confirm that the function is nowactive. Once activated only the initiating controller can then deactivate thisfunction?

To Deactivate the Child Lock

To deactivate the Child Lock function press the button for 3 seconds.The Child Lock indicator will go out to show that the function is nolonger active.

Child lock only applies to the water controller initiating the function and can beactivated / de-activated regardless of priority status or whether the water heater isin the ‘On’ or ‘Off’ condition.

While the child lock is activated only the ‘Child Lock’ control and the ‘Off’ control are functional from that controller.

When the water heater is turned ‘Off’ while Child lock is activated it can not be turned‘On’ again from a controller where the Child lock is activated.

If the water heater is turned ‘Off’ whilst hot water outlets are open it can not be turnedback ‘On’ until all hot water outlets have been closed.

Child lock is de-activated during a battery change or when batteries fail.

SMARTSTART® PRE-HEAT OPERATIONABOUT THE SMARTSTART® PRE-HEAT SYSTEM

Preheat FunctionThe “preheat” function works in conjunction with various Rinnai water heater models and theseparately installed and optional Rinnai “Smartstart®” module.

When the “preheat” function is activated and used in accordance with these instructions, water in thepipework connected between the water heater and the hot water outlets in your house is warmedbefore any outlets are opened. This results in water savings and added convenience.

The preheat function is activated as follows:

1. Ensure that the hot water unit is on (temperature digits are displayed in the digital monitor ).If more than one controller is fitted press the ‘Transfer’ button to pass on priority to yourdesired controller. The ‘Transfer’ indicator will illuminate to confirm that priority has beenassigned to this controller and that the hot water unit is ready to deliver hot water.

2. Select the desired temperature using the 'Temperature' buttons until the requiredtemperature is displayed in the digital monitor .

3. Press the ‘Preheat’ button once. The ‘preheat’ indicator and the ‘In Use’ indicator willilluminate, signifying that the preheat system has been activated.

4. Wait approximately two minutes before opening an outlet. This will allow the water in thepipework to be warmed.

Other Water Controller FunctionsWater controller functions such as temperature control and transfer of priority between multiplecontrollers are not affected by the operation of the preheat. Such functions are described in theapplicable sections of this manual.

The waiting time may be longer or shorter than two minutes depending on yourparticular installation configuration.

The preheat function is cancelled 5 minutes after activation and the ‘preheat’indicator will go out. This is to conserve energy. To reactivate, simply repeatsteps 2-4 above.

* If the ‘preheat’ button is pressed and the ‘Smartstart®’ preheat unit is notinstalled, the ‘preheat’ indicator will still light but there will be no preheat function.The ‘preheat’ indicator will go out after a short time and will not affect the otherfunctions of the water controller or water heater.

INSTALLATION MANUAL

INSTALLATION GENERAL
RINNAI WIRELESS WATER CONTROLLERS
A wireless water controller installation utilises a 'transceiver' and up to 4 wireless water controllers.Unlike most remote control systems, there is 'two way' communication between the transceiver andcontrollers. The 'transceiver' is connected by electrical cable to the water heater. The 'transceiver'transmits control signals received from the wireless controllers operated by the user to the waterheater. The 'transceiver' transmits operational 'status' signals from the water heater which arereceived by individual wireless controllers to ensure controller displays reflect the operational statusof the water heater.

Wireless water controllers can be installed in conjunction with Universal and Deluxe wired watercontrollers and will function as described in the Operation Section of this manual. Refer to page 2 toconfirm the maximum number and combination of water controllers that can be fitted.

Master and Sub controllers and temperatures Only one wireless or wired controller can be designated the 'Master Controller' (MC). This controlleris normally used in the kitchen and usually has a maximum temperature of 55°C, is sufficient foralmost all kitchen applications. Temperatures higher than 55°C are possible but usually unnecessaryand will result in higher gas use and increase the risk of burns. Some conditions regarding MasterController maximum temperatures are as follows:

• Temperatures of 55°C or higher can only be selected on the controller designated as MasterController (MC) if the transceiver 'Max Temp' is also programmed to 55°C or higher.

• The temperature of hot water delivered is always limited to the maximum temperature programmedinto the water heater itself. For example, if the transceiver maximum temperature is programmed to55°C and the water heater is limited to 50°C, the maximum temperature that the water heater willdeliver is 50°C. In this case 55°C will be displayed on the wireless Master Controller until a tap isopened after which the display will revert to 50°C.

The remaining controllers are designated 'sub' controllers and are for use in bathrooms, toilets andlaundries. The temperature limit for all 'Sub' controllers is always 50°C to minimise the risk of burns inthese areas.

Adhesive labels are included for individual identification of wireless controllers as master (Kitchen) orsub (Bathroom No.) controllers. These labels are usually placed on the top back of the wireless watercontroller body.

GENERAL INSTALLATION INFORMATIONRinnai Wireless Transceivers can be connected to the water heater models listed on the cover pageby the end user in accordance with these Instructions. These water heaters contain the ’Ezi connect’cable connector and a qualified tradesperson is not required.

Rinnai Wireless Transceivers are also compatible with some older water heater models not listed onthe cover page of these Instructions. Since older water heater models do not contain the 'Ezi connect'cable connector, wireless water controllers must be installed and commissioned by a suitably qualifiedand licensed tradesperson. Contact Rinnai for information regarding compatibility with older waterheaters.

The water heater maximum temperature cannot be adjusted by the user.These adjustments can only be carried out by a qualified and licensed tradesperson.

Other manufacturers water controllers are NOT compatible with Rinnai water heaters.Water controllers MUST NOT be used with any Solar Boost water heater. Rinnai watercontrollers brought in from other countries are not compatible with Rinnai appliancessold in Australia.

Regardless of water controller installation, all Rinnai water heaters must only beinstalled by an Authorised person.Water controllers, transceivers and water heaters do not contain user serviceableparts and must only be serviced and repaired by an authorised person.

IMPORTANT

NOTE

IMPORTANT


INSTALLATION GENERAL
POSITIONING OF TRANSCEIVER AND WIRELESS WATER CONTROLLERS
The water controllers must be installed in shaded and clean locations. The water controllers and thetransceiver should be fitted out of reach of children (suggested height from floor to be at least 1500mm).

The water controllers are water resistant, however, durability is improved when positioned outside theshower recess. The water controllers must be installed at least 400 mm above the highest part of asink, basin or bath.

The transceiver comes supplied with a 1.5m length of communications cable.

The transceiver’s antenna is located in the top. For the best results mount the transceiver so the topof the transceiver is higher than the top of the water heater. If the transceiver is mounted to the sideor below the water heater signal strength may be reduced.

The transceiver may be mounted inside metal recess boxes or pipe covers, however this may alsoreduce signal strength.

In some cases building construction and design can reduce signal strength and it may be necessaryto locate the transceiver in a central location inside the building. For such conditions extended lengthsof communication cable are available from Rinnai.

Take the signal strength into consideration when determinig the best location for both the transceiverand the wireless water controllers.

The MC-503RC Wireless water controller is a water resistant device, howeverexcessive exposure to water such as immersion may result in damage to thecontroller.

• DO NOT immerse the controller into water. • AVOID direct exposure to water or steam as these conditions may cause a

malfunction. • ALWAYS AVOID exposure to water when the battery compartment is open.

When cleaning your water controller use ONLY a damp cloth and a mild detergent.

Alternatively two core sheathed (double insulated) flex with minimum crosssectionalarea of 0.5 mm² may be used. Maximum individual cable runs should not exceed 20m.

NOTE

NOTE



COMMUNICATION CABLECONNECTING COMMUNICATION CABLES TO THE WATER HEATER

Communication cables connect the water heater to any wired water controllers and the wirelesstransceiver and operate at an extra low voltage (12 Volts DC) which is supplied from the water heater.Communication cables are supplied with the wired controllers (15m) and the transceiver (1.5m) andare fitted with spade terminals for connection to water heater. Up to two cables can be connecteddirectly to the ‘Ezi connect’ cable connector at the water heater. Extension cables are available fromRinnai. Alternatively, two core sheathed (double insulated) flex with minimum cross sectional area of0.5mm² may be used. Cable lengths must not exceed 20 metres.

To connect up to two cables to the ’Ezi connect’ cable connector

DO NOT attempt to connect cables to the 'Ezi connect' cable connector at the waterheater unless the electric power to the water heater is switched ‘off’ otherwise damageto electrical components may occur.If your water heater is not fitted with an 'Ezi connect' cable connector, installationmust be completed by a qualified and licensed tradesperson.

1. Isolate the electric power supply by switching the power point off and removing the power plug ofthe water heater from the electric power socket.

2. Remove the retaining screw of the 'Ezi connect' cable connector at the base of the appliance.

3. Swing the 'Ezi connect' cable connector door open and thread the cable through the weather sealof the cable access hole in the direction shown allowing sufficient cable length so that thesheath of the cable can be secured with cable clamp supplied with the transceiver.

4. Loosen screw terminals and and connect the cable spade connectors to these terminalsand re-tighten. Polarity is not important, either wire colour can be connected to either terminal.

5. Return the 'Ezi connect' cable connector to the original position taking care not to damage cablewires in the process and replace the retaining screw .

To connect three or four cables to the 'Ezi connect' cable connector, consult the“CONNECTING WATER CONTROLLERS” section of the water heater Operation /Installation manual supplied with the water heater.

NOTE

TRANSCEIVER INSTALLATION
MOUNTING THE TRANSCEIVER
• The distance between the water heater and the transceiver must not exceed 20m.• Metallic structures, appliances or magnetic fields in the vicinity of transceiver or

wireless water controllers may reduce signal strength.• Do not install transceiver near a heat source, such as a cook top, stove or oven. Heat,

steam, smoke and hot oil may cause damage. • The transceiver MUST NOT be installed where chemicals such as benzine, alcohol,

turpentine, hydrogen sulphide, ammonia, chlorine or similar chemicals are in use.

1. Determine the most suitable position for the transceiver (see “POSITIONINGOF TRANSCEIVER AND WIRELESS WATER CONTROLLERS” onpage 10).

2. The transceiver can be mounted to the wall using suitable screws or mountedto the side of the water heater via the strip of adhesive tape glued to the backof the receiver case.

3. If the transceiver is to be wall mounted, use the screws and/or anchorsprovided. Avoid over-tightening of fixings as this may cause damage. DONOT use powered tools to tighten fittings

4. If the transceiver is to be mounted to the side of the water heater perform the following steps:

a. Clean the side of the water heater where the transceiver is going to be mounted using a cleanrag with some methylated spirits or alcohol.

b. Remove the paper strip from the adhesive tape glued to the back of the receiver case to exposethe adhesive surface.

WIRELESS WATER CONTROLLER INSTALLATION
INSTALLING WIRELESS WATER CONTROLLERS
This installation procedure applies to wireless water controller installations only. Forcombined wired and wireless water controller installations refer to “INSTALLINGWIRED AND WIRELESS WATER CONTROLLERS” on page 14.Up to 4 wireless water controllers can be installed. Only one of these can bedesignated as a 'Master Controller' (MC), others will be designated as 'Sub' controllers.Only one wireless water controller can be installed at a time. DO NOT insert batteriesuntil step 3.

1. Ensure the power to the water heater is switched ‘on’.

2. Press the ‘Entry’ button on the transceiver for approximately 2seconds to select a wireless controller channel for tuning. The firstunassigned wireless controller channel LED will begin a fast flash,signifying that this channel has been selected for tuning.

The default order of channel selection is as follows: The wireless Master Controller is the only wireless controller capable of selectingmaximum delivery Temperatures exceeding 50°C. Ensure that the Master Controller(Kitchen) label provided is placed on the top rear of the assigned controller.

3. Select a wireless water controller for tuning to theunassigned transceiver channel and remove thecontroller from it’s wall mounting bracket. Openthe battery compartment with a full turn anti-clockwise. Insert the batteries observing thecorrect polarity. Close the battery compartmentwith a full turn clockwise

4. After battery installation the wireless controller will momentarily display an initialisation screen (A),which will then switch to screen (B) or (C).

5. If screen (B) is displayed press and hold the ‘On/Off’ button until screen (C) is displayed. Thistakes approximately 2 seconds.

6. From screen (C) press the ‘On/Off’ button once to start the tuning process which will takeapproximately 5 seconds. Once the controller is tuned the controller channel LED on thetransceiver will become steady and the controller LCD will switch to screen (D) or (E).

7. From screen (D) press the ‘On/Off’ button once or from screen (E) press the ‘Transfer’ button once to complete the tuning of this channel. At this point screen (F) will be displayed by thecontroller. The wireless water controller is now tuned and ready to control the delivery temperatureof the water heater.

8. Apply one of the self-adhesive identification stickers to the rear of the controller, ensuring that theMaster Controller sticker is only applied to the wireless water controller tuned to channel MC.

INSTALLING MULTIPLE WIRELESS WATER CONTROLLERS
To install subsequent wireless water controllers repeat steps 2 to 8 for each additional wireless watercontroller.

Once all wireless water controllers are installed re-secure the transceiver access cover.

TROUBLE SHOOTING WIRELESS WATER CONTROLLERS CHANNEL ASSIGNMENTIf at the end of the installation process screen (C) isdisplayed do the following:

Confirm first that the power is still on at the waterheater.

If power is off turn it back on. If the channel has beencorrectly assigned then the display should showeither screens (E), (F) or (G).

If screen (C) is still displayed un-installand reset the wireless controller andrepeat the installation procedure.

UN-ASSIGNING AND RESETTING WIRELESS WATER CONTROLLERS1. Press the desired controller channel button .

The LED will go out to signify that this channel isnow un-assigned.

2. Removing the batteries from the wirelesscontroller will reset the wireless controller andcomplete the un-install process.

INSTALLING WIRED AND WIRELESS WATER CONTROLLERS

When installing combinations of both wired and wireless controllers, all wired watercontrollers MUST BE connected before the wireless water controllers are assigned toa transceiver channel. Refer to page 1 to confirm the maximum number and combination of water controllersthat can be fittedWired water controllers can ONLY be added to an existing wireless installation when:• All wireless transceiver channels have been un-assigned.• All wireless controllers have been reset.See “UN-ASSIGNING AND RESETTING WIRELESS WATER CONTROLLERS” above.

When the wireless transceiver is installed it automatically detects any wiredwater controllers already connected to the water heater.

The LEDs of the channels assigned to wired controllers will slow flash.The channels for wired water controllers are assigned in sequence asfollows:

MC100V or MC91 (programmed as a Master Controller) will automaticallybe assigned to the MC channel.

BC100V or MC91 (not programmed as a Master Controller) willautomatically be assigned to an available channel other than the MCchannel.

Install the wireless water controllers to any of the unassigned channelsfollowing steps 1 to 9 on page 13.

MOUNTING THE WIRELESS WATER CONTROLLER
• Metallic structures, appliances or magnetic fields in the vicinity of transceiver orwireless water controllers may reduce signal strength.

• Do not install wireless water controllers near a heat source, such as a cook top, stoveor oven. Heat, steam, smoke and hot oil may cause damage.

• Do not install wireless water controllers in direct sunlight.• Do not install wireless water controllers outdoors unless protection from dust

ingress and sunlight are provided.• Wireless water controllers MUST NOT be installed where chemicals such as benzine,

alcohol, turpentine, hydrogen sulphide, ammonia, chlorine or other similar chemicalsare in use.

1. Determine the most suitable position for the water controller (see “POSITIONING OFTRANSCEIVER AND WIRELESS WATER CONTROLLERS” on page 7).

The ‘Signal Strength’ indicator displays one of four levels.

The ‘Out Of Range’ indicator displays when the wireless water controller is out of range of thetransceiver or when an object is obstructing the radio signal.

Wireless water controllers should be positioned such that the signal strength indicator displays atleast ‘2 bars’ next to the antenna symbol during installation. Signal strength varies withatmospheric and other conditions. If the signal strength is weaker than ‘2 bars’ during installation,there may be other times when the signal is too weak to allow operation.

2. Slide the wireless water controller from its’ wall mounting bracket.

3. Use the wall mounting bracket as a template to mark off and drill 2 holes for use with mountingfixings.

4. Secure the wall mounting bracket to the wall with the screws and or anchors provided. Avoid over-tightening of fixings as this may cause damage. DO NOT use powered tools to tighten fixings.

5. Slide the wireless water controller back into its’ wall mounting bracket.

ADDITIONAL WATER CONTROLLER MOUNTING CONSIDERATIONS.The MC-503RC uses a Liquid Crystal Display (LCD) for the digitalmonitor. Light reflections can make the LCD difficult to see at directeye level. For best results when Installing the MC-503RC mount the remotecontroller lower than your eye-level to avoid these light reflections.
